Abstract :
Two assembling methods, i.e., the sputter brazing method and the diffusion brazing method, have been developed for improving the heat dissipation capability of the helix traveling-wave tube slow-wave structure (SWS). The magnetron sputter plating technology and the pressure diffusion technology are employed in this letter to complete the SWS assembly. The effect of these two methods on the thermal conduction of the SWS was verified by several experimental tests. These two methods being pursued enable better heat dissipation capability of the helix SWS, compared to the conventional nonbrazing methods.
